    i tried, and failed

    isnt x to any constant equal to dy/dx

    is d/dx the same as dy/dx making it 4-3x

    Where? The only thing I see is
    isnt x to any constant equal to dy/dx

    is d/dx the same as dy/dx making it 4-3x
    Two questions, no work.

    The first suggestion was that you use the "fundamental theorem of calculus". You said "I tried and failed". HOW did you try? What answer would the fundamental theorem give you?

    woudn't it just be (4-3x)(1) yielding 4-3x since it's going from a constant to x.

    that is my work..
